Linux mainline fork with MSM8998 patches | https://mainline.space | Currently supported devices:
OnePlus 5/5T, Xiaomi Mi 6, F(x)tec Pro¹ (2019 QX1000 model) & Sony Xperia XZ Premium (UNTESTED!)
There are number of problems with configuration peer
network device in absence of IFLA_VETH_PEER attributes
where attributes for main network device shared with
peer.
First it is not feasible to configure both network
devices with same MAC address since this makes
communication in such configuration problematic.
This case can be reproduced with following sequence:
# ip link add address 02:11:22:33:44:55 type veth
# ip li sh
...
26: veth0@veth1: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \
noop state DOWN mode DEFAULT qlen 1000
link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
27: veth1@veth0: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \
noop state DOWN mode DEFAULT qlen 1000
link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
Second it is not possible to register both main and
peer network devices with same name, that happens
when name for main interface is given with IFLA_IFNAME
and same attribute reused for peer.
This case can be reproduced with following sequence:
# ip link add dev veth1a type veth
RTNETLINK answers: File exists
To fix both of the cases check if corresponding netlink
attributes are taken from peer_tb when valid or
name based on rtnl ops kind and random address is used.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
